TPS3110K33DBVR Description

Specifically for DSP and processor-based systems, the TPS3110K33DBVR families of supervisory circuits offer circuit startup and time supervision. RESET is asserted low during power-on when the supply voltage (VDD) rises above 0.4 V. The supervisory circuit then keeps an eye on VDD and maintains a low RESET output as long as VDD is below the threshold voltage (VIT-). After VDD exceeds the threshold voltage, an internal timer delays the RESET signal's shift from low to high for the predetermined amount of time to ensure proper system reset. VDD shifts back to low when it falls below VIT-.
